IMPROVEMENT IN ICARBURETERS.

Specification forming part of Letters Patent No. 180.06l, dated July 18, 1876 application filed January 3, 1876,

To all whom it may concern:

Be it known that we, JAMns M. POLLARD, of New Orleans, parish of Orleans, State of Louisiana, and WALLACE R. BARTON, of Gal.- veston, county of Galveston and State of Texas, have invented a new and useful Improvement in Carburetors; and we do hereby declare that the following is a full, clear, and exact description of the same.

Our invention is an improvement in the class of gas-carburetors in which the apparatus is submerged in water for the purpose of equalizing the temperature of the carbureting-liqnid, and thereby imparting a more uniform illuminating quality to the gas; also obviating the danger of explosion from access of flame to the exterior of the apparatus.

The invention relates to the construction and arrangement of parts, hereinafter dc-v scribed, and specified in the claims.

In the accompanying drawing, formin g par of this specification, Figure 1 is a sectional elevation of our improved apparatus, and Fig. 2 a horizontal section of the earbureting-cylinders. Fig. 3 is a cross-section of the apparatus, taken online a; w of Fig. 1.

The carbureter proper is constructed of two I or more parallel horizontal cylinders, A B,

connected at one end by the pipe 0, and tightly packed around the inside with asbestus or other suitable material, leaving a longitudinal cylindrical space throughthe center,

which is closely filled with parallel strips of cloth a, or equivalent strips offibrous material.

The gas enters cylinder B at the point a through pipe D, passes through the absorbent therein, and, by pipe G, into the second cylinder A, from which it escapes at a through pipe E. The carbu'reting-liquid enters the carbureter, from the reservoir F, at the point 0, near the end of cylinder B, and adjacent to the exit of the gas. After saturating the ab- I sorbent therein it passes through the pipe 0 into the second cylinder A, and reaches the point a, at which the gas enters the carbureter. The liquid and gas thus flow in opposite directions through the whole length of the carbureter, from which it results that the least vaporizable portion of the liquid is caris vaporized, and no residuum left-- a result economically important.

In order to regulate the escape of liquid from the reservoirF to the cylinders we employ a float, d, provided with a vertical rod, 6, working in a 'tube,f, and operating a valve, g, as will be readily understood by the drawmg.

The eduction and induction pipes D E, Fig. 3, rise vertically from the respective cylinders A B, and are connected by a tube and stopcock, (not shown,) whereby the whole or a portion of the gas may be allowed to pass without entering the cylinders.

The whole apparatuscylinders, reservoir, and gas supply and discharge pipes-is secured to the bottom of a tank, Gr, made sufficiently larger than said apparatus to admit a large body of water on all sides of it, and between it and the tank. From the pipe D an open drip-pipe projects downward into the water to aconsiderable depth.

It is apparent that so much of the gasoline as condenses in the pipes and flows back toward the carbureter will rest on the surface of the water in the drip -pipe J, till, overflowing the upper portion of said pipe, it returns to the carbureter proper. This it does by its lighter specific gravity. If, on the other hand, water of condensation enters the drippipe, it necessarily sinks to the level of the body of water in the tank G, which the gasoline cannot do. This prevents access of tire to the carbureting apparatus, and thus insures its safety from tire under most conditions, as well as renders the temperature of the carbureting-liquid more uniform, thereby favorably affecting the stable quality of the gas.

or vessel, which has a discharge-tube, which In order to fill the carbureter, we use a can 7 through cock 6, end when the filling is completed the vessel I is resupplied with water to the requisite depth.

The box-is provided with an annular groove, L, into which a flange, M, forming a part of the cover, projects. The groove L being filled with water, the whole is water-sealed.

What we claim is--= 1. The drip-pipe J, pendent from that part of the gas-conducting pipe E which is above the body of water in the tank, and extending down into the water, as shown and described,

for the purpose specified. 4

2. The combination, with the hydrocarbonreservoir, provided with the filling-tube H, of the cylinder, containing the liquid seal, and provided with a cock for discharging the liquid, as set forth and described.
